| Abstract: | There exist randomness both in earthquake actions and in structural performance;therefore,the seismic reliability analysis of structures should be done to assess seismic performance of structures.Two new numerical simulation methods for structural reliability analysis are proposed,which include uniform design response surface method(UDRSM),and hybrid simulation method(HSM) combing Monte Carlo Simulation(MCS) and UDRSM.Theses methods are all implemented in ANSYS by using deterministic finite element method.T... |
